The Secret Of Stradivarious Violins Has Been Discovered

The chemistry is the key to the special sound from the violin made in the eighteenth century by the Italian Antonio Stradivarius, shows the latest edition of the British Journal Nature.

Among the various hypotheses to explain the peculiar sound of the instrument appeared one, according to which a special material would have been used in their manufacture.
Another hypothesis advanced indicated that the sunlight in the XVII and XVIII was lower, so that the trees grew less and its wood was more dense, which creates higher acoustical properties.
The study, conducted by experts at the University of Texas, in the United States, indicates that the wood used in these violins has been the subject of a chemical treatment in order to preserve the characteristics of the sound.
The oxidation and hydrolysis were the methods applied.
The research shows that the same chemical treatment was applied to Guarneri violins manufactured by the family of Cremona (Italy), which are considered almost as valuable as the Stradivarius.
To reach their conclusions, the researchers resorted to chips of wood withdrawals of five instruments that were being repaired.
We them a Stradivarius violin in 1717, a Stradivarius cello of 1731, a Guarnerius violin in 1741, another manufactured in Paris in the decade from 1840 by Ghent-Bernardel and a viola executed by Henry Jay in 1769, in London.
The comparison between the five instruments, was made through infrared spectroscopy and nuclear magnetic resonance, showed that in the manufacture of violins, had been used chemical treatments, something that is not registered on instruments from Paris and London.
